I am really enjoying this discussion, because of the way it merges personal reflection with theoretical knowledge (a convergence that Twitter and Facebook provide precisely because the same people post such widely varying comments- from food-related ones to academia-related ones). I wonder how much of what is posted on Twitter and Facebook is a response to the way in which the updates are elicited. On Twitter, the question above the comment box asks: what are you doing? Naturally people respond accordingly. On Facebook, the question is: what's on your mind? With regard to food, both sites get posts about culinary experiences, but perhaps they are presented differently partly because of the way the information is framed by the question. Selected audience also might be a factor, as some have expressed so well on this list. When I make a post about food, I address a part of my total potential audience base. When I post about movies, it might be another part. Posts about my kids go out to yet another part. The point is that people can choose to read or to ignore. That is the beauty of social media- active choice. I have to say my pet peeve with regard to Twitter so far is that when people try to squash all their ideas into 140 characters, sometimes I can't figure out what they are actually trying to say!
